I cannot attach the 4th motor joint(the end effector rotation motor). I tried attaching it using gcode “M2201 N3” and checked the status using gcode: “M2203 N3” and got a reply “ok V0” indicating it is detached. All my other motor joints attach and detach except for this one.
I can move the 4th motor to a desired angle using gcode, but it fails to remain attached.
Hi, I’m having the same problem and it affects the capabilities of the uArm Swift Pro since the 4th motor joint makes unexpected movements while the arm is making some other taks like draw or laser engravement, which ruins all the work done.
